XSLP_FILTER

Bit map for controlling solution updates

Integer

Bit	Meaning
0	retrain solution best according to the merit function.
1	check cascaded solutions against improvements in the merit function.
2	force minimum step sizes in line search.
3	accept the trust region step is the line search returns a zero step size.

11 (bit 0,1,3)

Bits 0 determine if XSLPgetslpsol should return the final converged solution, or the solution which had the best value according to the merit function.
If bit 1 is set, a cascaded solution which does not improve the merit function will be rejected (XSLP will revert to the solution of the linearization).
Bits 2-3 determine the strategy for when the step direction is not improving according to the merit function.

The following constants are provided for setting these bits:

Setting bit 0	XSLP_FILTER_KEEPBEST
Setting bit 1	XSLP_FILTER_CASCADE
Setting bit 2	XSLP_FILTER_ZEROLINESEARCH
Setting bit 3	XSLP_FILTER_ZEROLINESEARCHTR
